0,5 ohm coil with Dyna 2000i ignition??
 

Hello, only a question. It is possible to use a TwinCam Single Fire coil with 0,5 ohm resistor, adding in series 2,5 ohm resistor in each side? If it is possible, te value of the resistor need to be 1w or more value?

Thanks.

in electronic energy transfer, the load must be balance for max effect.
it is best to match drive with load. if you add resistors in series, you can achieve the resistance value but the voltage drop across the load will be not the same as using the right coil. if voltage is lower, so is saturation and so is lower coil output.
look at a stereo system.
a stereo rated for 4 ohm driving a 8 ohm speaker will not over load the drive but since voltage is lower, the sound will be muddy.
if you take a 8 ohm stereo and drive a 4 ohm speaker, the voice coil in the speaker will be over driven and with volume cranked up, possible to damage the speaker.

It won't work. Newer ignitions sense crank spin to set dwell time and make it short. Older systems can use a longer dwell with the possibility of making the dwell time real long. (ignition on, crank stationary ) You can't have a long dwell time on a 1/2 ohm coil. You'll let the smoke out.. Adding a resistor only kills the performance of the coil and it will have quite a weak spark if any as there isn't enough current to saturate the coil.

Thank you very much for the clarification. I'm not very skilled at igniting. They gave me a single fire TwinCam coil and I had this crazy theory.
